phuryn/pm-skills is a marketplace of reusable skills, commands, and plugins that guide AI assistants through product-management work such as discovery, strategy, planning, metrics, launches, and growth. It is for product managers and teams using Claude Code, Cowork, or compatible assistants. The catalogue entries are the project's own workflows and extensions.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.00492 |
| Opus 5 | $0.00024 | $0.00246 |
| Sonnet 5 | $0.00010 | $0.00098 |
| Haiku 4.5 | $0.00005 | $0.00049 |
Grade A, and why
brainstorm-ideas-new scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Brainstorm Product Ideas (New Product)
Multi-perspective ideation for initial product discovery of a new product. Generates specific feature ideas from PM, Designer, and Engineer viewpoints.
Context
You are supporting initial product discovery for a new product: $ARGUMENTS.
If the user provides files (market research, competitive analysis), read them first. Use web search to understand the market if needed.
Domain Context
Initial Discovery vs Continuous Discovery: Initial Discovery focuses on vision, business model, and market validation — you're testing whether the product should exist. Continuous Discovery runs in parallel with delivery — you're constantly learning and iterating on a live product. This skill is for initial discovery.
Instructions
The user will describe their target segment, opportunity, and desired outcomes. Work through these steps:
-
Understand the opportunity: Confirm the product concept, target market segment, and what the users want to achieve.
-
Ideate from three perspectives — generate 5 specific feature ideas each from:
- Product Manager: Focus on market fit, value creation, and competitive advantage
- Product Designer: Focus on user experience, onboarding, and engagement
- Software Engineer: Focus on technical innovation, API integrations, and platform capabilities
-
Prioritize the top 5 ideas across all perspectives. For a new product, weight heavily toward:
- Core value delivery (does it solve the primary problem?)
- Speed to validate (can we test this quickly?)
- Differentiation potential
-
For each prioritized idea, provide reasoning and key assumptions to test.
Think step by step. Save substantial output as a markdown document.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

brainstorm-ideas-new is a skill published in the GitHub repository phuryn/pm-skills (26,507 stars, last pushed 7d ago), licensed MIT. It adds 49 tokens to every session and 492 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-15.
